Identification of Single Molecules in Aqueous Solution by Time-Resolved Fluorescence Anisotropy

Using a confocal epi-illuminated microscope with a polarizing beam splitter and dual-channel detection of single-molecule fluorescence induced by pulsed laser excitation, a new application of the three-dimensional, real-time spectroscopic technique BIFL (burst integrated fluorescence lifetime) is in...

description Using a confocal epi-illuminated microscope with a polarizing beam splitter and dual-channel detection of single-molecule fluorescence induced by pulsed laser excitation, a new application of the three-dimensional, real-time spectroscopic technique BIFL (burst integrated fluorescence lifetime) is introduced. BIFL allows simultaneous registration of fluorescence intensity, lifetime, and anisotropy. It is shown to be well-suited to identify the freely diffusing fluorescent molecule Rhodamine 123 and the Enhanced Yellow Fluorescent Protein via their characteristic fluorescence anisotropy using a time-resolved analysis. Furthermore, data analysis is discussed and rotational correlation times of single molecules are determined. Applications for multidimensional single-molecule identification are outlined.
